Project 321 began as a company with limited offerings of high quality Lefty hubs manufactured in the USA to meet a niche market. They combined their expertise in high precision CNC machining with innovative hubshell and gearbox designs to bring their latest line of hubs to market.

Hubs are fully serviceable with standard tools for many years of demanding use. All Project 321 hubs are 100% designed, manufactured and assembled in Bend Oregon and carry a 10-year warranty on hub shells.

Ti Bolt comes with an O-ring, Delrin washer, and 6.5cc Anti-seize Lubricant packet for use during installation.

Ti bolt torque is 133 in./lbs as recommended by Cannondale.

Torque is lasered on bolt for convenience.

Inventory Note:We stock a wide variety of Project 321 hubs, however our inventory fluctuates daily. We may need to order hubs with an average lead time of 2-7 business days. Some hubs may take longer. If your order is time sensitive we encourage you to contact us for up to the minute product availability and shipping lead times.
